Climbing rose plant named &#39;RADWIRE&#39;

ABSTRACT

A new and distinct variety of climbing rose plant herein referred to by its cultivar name, ‘Radwire’, is provided which forms in abundance on a substantially continuous basis attractive, cup-shaped, deep pink blossoms. The vegetation is vigorous and the growth habit is very bushy and climbing. Attractive, semi-glossy, medium green foliage is formed. Excellent disease resistance is exhibited, particularly for black spot, rust, and mildews. The new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Botanical/commercial classification: Rosa hybrida/Climbing Rose Plant.

Varietal denomination: cv. Radwire.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Climbing rose plant of the present invention was created in June 2006 at Greenfield, Wis., U.S.A. The seed that produced the new variety of climbing rose plant was from mixed parents of unreleased and unnamed breeding parents (each non-patented in the United States). No further definitive information concerning the identity of the parents is available.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Climbing rose plant of the present invention possesses the following combination of characteristics:

(a) abundantly and substantially continuously forms attractive, cup-shaped, deep pink blossoms,

(b) exhibits a very bushy and climbing growth habit,

(c) forms vigorous vegetation,

(d) forms attractive, ornamental, semi-glossy, medium green foliage,

(e) exhibits excellent disease resistance, particularly with respect to black spot, rust and mildews, and

(f) is well suited for providing attractive ornamentation.

A new rose variety is provided displaying attractive, cup-shaped, deep pink blossoms combined with substantially continuous blossoming and excellent disease resistance.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings to cover a trellis, arbor, or fence. Accordingly, the plant is particularly well suited for growing in the landscape where a climbing rose plant is desired.

The new variety can be readily distinguished from other climbing roses such as ‘Radwin’ (U.S. Plant Pat. No. 19,310) in that the new variety exhibits a bloom color that is deep pink as opposed to the red colored blossoms of the ‘Radwin’ variety.

The new variety can also be distinguished from another climbing rose such as ‘Margaret Mae’ (U.S. Plant Pat. No. 20,953) in that ‘Margaret Mae’ displays many more petals, upwards of 70-80 petals, versus only 18 petals on the new variety.

The characteristics of the new variety have been found at Wasco, Calif., U.S.A., to be homogeneous and stable and to be strictly transmissible by asexual propagation, such as budding, grafting, and the rooting of cuttings from one generation to another. The new variety reproduces in a true-to-type manner by such asexual propagation.

The new variety has been named ‘Radwire’, and will be marketed under the Highwire Flyer™.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, typical blossoms of the new variety. The rose plant of the new variety illustrated herein was approximately three years of age and was grown outdoors on its own roots in West Grove, Pa., U.S.A. when it was observed in June 2015.

FIG. 1 shows a close view of the blossoms and foliage of the new variety.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—2015 Edition), London, England.

The description is based on the observation of two-year-old specimens of the new variety during June while growing in ground on their own roots at West Grove, Pa., U.S.A.

Plants of the ‘Radwire’             variety have not been observed under all possible             environmental conditions to date. Accordingly, it is             possible that the phenotypic expression may vary somewhat             with changes in light intensity and duration, cultural             practices, and other environmental conditions.
